In-N-Out Burger, the popular West Coast fast-food chain, just added hot cocoa to its menu — the first new permanent menu item in over a decade. Last time it altered its notoriously simple menu was when it added lemonade back in the early 2000s.

The new beverage is made with cocoa powder from Ghirardelli Chocolate Co. — another California-based company — and costs $1.60 for an 8-ounce cup or $2.65 for a 16-ounce cup, according to a customer service representative. Of course, prices may vary by location.

To make this drink’s release even sweeter, In-N-Out has a special on this tasty treat for the kiddos on rainy days.

When It Rains It Pours… Hot Cocoa

Time to start practicing your best rain dances, kids. Because when it rains, it pours… free hot cocoa at In-N-Out Burger for kids 12 and under. Now those rainy days mean something extra sweet for the kiddos.

Keep in mind, though, the kiddos have to be there to claim their freebies. So no leaving the troops at home while mom goes to In-N-Out and fills all the minivan cup holders with that hot, steamy, chocolatey goodness. One good thing, though: There is no expiration date on this deal.

In-N-Out Burger couldn’t confirm what size the freebie would be, so your mileage may vary from restaurant to restaurant.

We’ll tip our cups to this no-strings-attached freebie and try not to be jealous of the fine folks in California, Texas, Oregon, Arizona, Nevada and Utah.

So next time it rains, don’t wait for the storm to pass. Put on your rain shoes and run over to a participating In-N-Out Burger near you.
